Find a link that has the high rez pictures of K-1, DFA 24-70, DFA* 70-200 and mounted with few other lenses(yes FA limited are there) compared to few other brand's cameras and their 24-70 and 70-200 and other lense. Pretty cool size reference and seeing the K-1 mount different lenses in those pictures!
Also there is a picture of DFA 24-70, Canon 24-70 L II, Sony FE 24-70 G Master and Nikon 28-70 in there. And another picture of Pentax , Canon Nikon 70-200 size comparison there.
Especially like the K-1 with A900 pictures, looks like brother cameras in arms
PS the link is in Chinese, but just enjoy the pictures should be OK.
Enjoy!
